HI my name is Joao, i have a sony vaio pcg 61211m and recently i broke the screen, i order a new one from ebay and replaced it, the problem is i can see something on the screen but the image is too dark and even if a change the brightness it doesn't help..

 

I dont know if i need to buy anything else beside the screen... if someone could help i would aprecciate it.

    Hi Joao and welcome.

     

    Is the image very dark?  It sounds like the backlight is not working.  Perhaps you have disconnected the wiring to the inverter when you changed the screen? 

     

    Does the image appear normal on an external monitor?

     

    It looks like you may have to take the screen apart again to recheck the wiring or replace the inverter.

    The inverter will look something like this:

    It will have a cable connection at both ends – left side to video cable and right side to the backlight tube.

     

    You would presumably have to of disconnect this when removing the old screen...

     

    If it is present and connected properly there is a possibility that it is faulty or one of the ribbon cables is damaged.

    Hi  Joao,

     

    Yes there is a strong possibility that there is no inverter as it's LED and would therefore use DC power, but may have some sort of controller board - sorry I have no experience of these screens...

    Hi Joao,

     

    As stated previously I have no experience with LED screens but research suggests that there is a possibility that either there is a fault with the cabling or, more likely, a fuse on the motherboard has blown.

     

    The following thread from Notebook Review refers to a Dell model but presumably the technology will be similar and may throw some light (no pun intended) on your problem.

    I would first try another screen if the supplier is willing to exchange at no cost and if this still fails to work then contact a competent repairer.

    Good luck Joao, and please let us know the outcome as this will no doubt be of help to other members.
